Answer:
unlike terms is the answer
Answer:
10,100,1000,-10,-100,-1000
Step-by-step explanation:
Best Answer: Bill's time to do the whole job, B
Jeff's time, B + 5
time they actually work, 6.
6/B + 6/(B+5) = 1
6(B+5) + 6B = B(B+5)
6B + 30 + 6B = B² + 5B
B² - 7B - 30 = 0
(B - 10)(B + 3) = 0
B = 10 or B = -3, and we reject the negative solution.
the equation is based on adding the fractions of the whole job each does. if Bill takes B hours to do the whole thing and works 6, he does 6/B of the job. similarly for Jeff.
in the 2nd problem,
a = time of experienced accountant
2a = time of new accountant
10 = time each actually works
10/a + 10/(2a) = 1 ........ multiply all by a
10 + 5 = a
a = 15 hr.
Answer:
distribute first so it would be 18x-42=2
Step-by-step explanation:
Answer:
The slope of this line would be 3.
Step-by-step explanation:
To find the slope of any line, use the slope formula and the points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(3 - 2)
m = 3/1
m = 3
